I've gone to three different Home Depots and a fourth smaller hardware/garden store and none of the customer service people seem to know what a quarry tile is or how to identify it. The closest thing I can find looks like poured unglazed concrete tiles. I know I'm supposed to get an unglazed "quarry tile" as a possible pizza stone solution, but where the heck do I actually buy one and under what name/brand/description do they show up in retail or hardware stores? No one in the hardware nor garden supply centers of the hardware stores knows what I'm talking about. I'm in the Los Angeles area.
Hope someone can help, thanks.
